Figure 10 is a section taken at the 5 earth, in transferring minerals, such as coal, line 10 on Fig. 9 and viewed in the direction from one point to another, and in the conof the arrow; and Figure 11, a broken, enveying of materials in general, and involving larged elevational View of a derrick forming in such transferring operation along a prea part of the apparatus of Figs. 8 and 9. determined path, a change of direction of Referring to Fig. 1 of the drawings, this 1o movement of the scraper either in a sub- View shows a portion of a mine, as for examstantially horizontal or vertical plane. plc a coal mine, 12 representing the face of My object, generally stated, is to provide the body of coal being mined, the dislodged a novel, simple and inexpensive construction coal in the mining operation falling onto the of apparatus by which, under the control of floor 18 of the mine adjacent the face 12 and 15 an operator, the scraper may be caused to from which it is desired the coal be moved travel in such a path, without producing undown the gallery 14 to the gallery 15 for dis due wear of the parts of the apparatus and charge into a receiver ll shown as a chute be operable at different speeds without refor directing the material into a car, (not quiring expensive machinery; and other obshown), operating in the gallery 15 on tracks 20 jects will be manifest from the following 16 therein, it being understood from the foredescription. going that in transferring the coal from the Referring to the accompanying drawings: face 12 through the gallery l l to the point of Figure i is a plan sectional view of a pordischarge, it is moved along a predetermined tion of a coal mine equipped with apparatus, path with portions of the path extending at constructed in accordance wit-h my invention, angles to each other in a substantially horifor transferring the loose coal deposited on Zontal plane due to the necessity of carrying the floor of the mine in the mining operahe coal around the corner 17 of the mass 18 tion, to a point of discharge and involving of unmined coal.

the transferring of the coal along a prede The apparatus by which the mined coal so termined path, portions of which extend at conveyed as stated and embodying my inan angle to each other in a substantially horivention comprises a scraper 19 which may be zontal plane. Figure 2 is a perspective view of any suitable type, as for example of the of the scraper portion of the apparatus and so-called bottomless-scraper type, connected illustrating one form of embodiment of my at its forward, filling, end with an inhaul line invention. Figure 3 is a plan view of a 20; at its rear end with a baclnhaul line 21 modification of the scraper device. Figure d and operatively associated with a third line is a view in side elevation of the structure 22 as hereinafter described. The inhaul line shown in Fig. 3. Figure 5 is a plan view of 20 is shown as engaging a sheave and still anothei modification of the scraper dethence to a winding drum 24L to which it is to vice, igure 6 is a view in side elevation connected. The back-haul line 21. is shown of the apparatus of Figure 7 is a as p ssing around a sheave 25 secured to an broken, enlarged sectional view of a portion adjacent wall 26 of the mine, and preferably of the structure shown in Fig. 5, the section adjustable, in any suitable way, lengthwise being taken at the line 7 on 5 and viewed along the wall 26, this line also engaging a 5 in the direction of the arrow. Figure 8 is an sheave 27 secured to the adjacent wall 28 of elevational view, somewhat in the nature the mine and adjustable in any desirable of a diagram, of apparatus for excavating way along the latter, this line thence extendearth and involving, in such operation, a ing into engagement with sheaves 29 and 30 chan. in direction of movementof the and to a winding drum 31 to which it is conscrape. in a substantially vertical plane, the nected. The line 22 engages a sheave 32 seapparatus being shown in operative position cured to a wall 33 of the gallery 14 in any Referring now to the operative 1:0111-1ectio1r of the line 22 with the scraper apparatus l9, Fig.2 shows a well-knmvn type of so-called bottomless scraper, the line being connected with the forward end of the scraper through the nediun' of a clevis 37 and a bridle 38 the sections of wl'iich' connect with the forward extremities of the sides of the scraper, the line 21 being connected with the rear endof the scraper midway between the of thelatter through the niedii. u of a bracket 39. l its opposite de- Connectee as pending arms iOnand ill with the clevis 37 and rigidly with the bracket 39-, respectively,

42 which is preferis a yoke-shaped slideway ably slightly flexible and to this end may be made of steel, this yoke beii'ig preferably provided with a stop button l3 on the-rear arm f ll, The Sll(il6-."?.y 4:2 is tluiis positioned above the scraper l9 and extends preferably substantially parallel with the longitudinal axis of the scraper and midway of the sides of the latter. The hauling line operatively en.-

thc scraper 19 through the medium of the slideway 41-11 the connection between these parts being eta ring 44: connected with the line 22 and surrounoin 1 the slideway l2 along which it is slidable from the clevis to the stop 4:3,.

in the operation of the apparatus for aferrinp; coal from the face 12 to vthe chute i l, and assuming the parts-elf theapparatus,

to he in the poukiou shown in l, the winding drum 36 actuated to draw on the line 252 which latter in engi gipgingz the are]. eeO drags the srru-iwr from its front end alone; the coal to be transferred, the drum; 2-4: in this operation being; driven. to take up the slack in line E20 and the drum ill being; left free to rotate so that the line ill may pay out i u this movement of th 19 reaches 14-, the operator actuates thereby draw the scraper down he zvilery 1st to the chute i l? by means of the line I.

the line 21 continuing to pay out and th druin 36 being; conditioned to it the line to pay out a The return of the scraper 19 to fillinr s ion at the face 12 of ti mine is ef' -v cte d by draw wardly along the gallery 1* yond the face 12 by drawi on theline the line 20 paying;- out .7 Aion and the drum 31 being actuated to tar-re up the a pm on beslack in line 21,it being understood that in the movement of the scraper 19 into the gallery let the line 22 runs along the slideway to the rear end of the scraper until it engages with the stop 43 and thus when the line 22 is drawn :pon stated it engage the stope3 and thereby operates as a baclohaul line. Upon con'ipleting the return movement of the scraper 19 to a position beyond the face 12 by o erating the line 22 as stated, the line 2i is operated,both lines 20 and 22 paying out in this operation to drag the scraper backwardly along the face 12 to filling position.

it will thus be understood from the foregoing description that the line operates alternately as an inhaul line and a hack-haul line, the inhaul function being performed in the movement of the scraper along: the face of the mine to a point beyond the corner 1'? and the baclohaul function being); performed in the moving of the scraper baelo weirdly from its point of discharge along the gallery l-l to a position beyond the face 12, the arrangement provided for causing the scraper apparatus to function as stated not only being of simple and inexpensive construction and positive in operation, but overeoinii'sp; the necessity of drawing any of the lines in taut condition m aiust the cornerportion of a mass of material. V

lip;s. 8, 4:, o 6 and 7 show n'iodilications of the slideway by which the automatic shifting of the line 22 relative to the scraper to cause this line to function alternately as an inhaul and a back-haul line, is eli'ected, In the construction shown in 3 and i the slideway represented at lli and shown as of general yoke form is secured to the scraper l9 wl'iolly independently of the lines 20 and 21 the front end of this yolce being directly connected with the tin-ward extremities of the side of the scra er 19 through the medium The slideway of lilo struciion is rcpres' nted at 59 and is shown as iorn'ied of a oke-bar substantially it shape in cross SGLLlOll alfording upper and lower grooves 51 and 52 in which rollers and 5% j ournalied in a elevis 5 and connected with. the line are confined. The slidewey which extends from the rear end ot the scraper substantially from ape-int inidw v between the sides thereof to a point at the front end of the scraper substantially coincident with the longitudinal axis of the scraper, is located substantially midway between the upper and lower edges of the scraper, the forward end of this guideway being provided with an eye 56 for attachment thereto of the line and its rear end provided with an eye 5''? for attachment with the line 21, a bar 58 connected with the eye 56 and with the side of the scraper opposite that at which the slideway extends, serving, in connection with the forward extremity of the slideway 50, to equalize the pull on the scraper when the scraper is being pulled by the line 20. Preferably the forward ends of this scraper are braced, as for example by the cross member represented at 59.

The sheaves 25 and 32 being adjustable as stated permit of the changing of the angle of the path through which the scraper is operated, as desired, and. the changing of the path through which the scraper moves in traversing the face 12 of the mine, to cause the scraper to be operated along this face as the latter recedes in the mining operation.

My invention is useful not only where the scraper in its movement in a predetermined path involves a change in direction of t 'avel in a substantially horizontal plane as described, but also where such change of direc tion is in a substantially vertical plane as for example in the case of excavating earth in which connection it is illustrated in Figs. 8, 9, 10 and 11. In these figures the earth is shown as being excavated at 60, the side wall of the excavation being shown at 61 and the spoil pile at 62, the operation of producing the excavation 6O involving the dragging of the scraper along the substantially horizontal bottom of the excavation and thence upwardly along the side 61 thereof to the spoil pile, there being thus provided a corner portion represented at. 64 at the juncture of the wall. 61 and the lever of the earth adjacent the excavation.

In the arrangement shown the scraper is represented at 66, its for *ard end connected with an inhaul line (37 engaging a sheave 68 supported on a travelling carriage 69 and extending into engagement with a sheave 70 on a derrick 71 and thence to a winding drum 72. lhe rear end of the scraper is connected with a hack-haul line 3 running over a sheave 1 1-. secured to a carriage T5 located in the excavation (it). and thence over a sheave 75 on the derrick "ii to a \vindii'ig drum 7'? to which it is connected. The apparatus also involves a line 78 "which has sliding engagement with a slideway rep resented at 79 and operatively connected with the scraper 66 as explained of the construction shown in 1 and 2, this line running over a swiveled flexibly-hung sheave 80 supported on the derrick 71 and thence leading to a winding drum 81 to which it is connected.

Assuming the various parts to be in the various positions shown in Figs. 8 and 9, to

return the scra'per 66 to excavating position, the line 78 is drawn on and the line 67 paid out and the slack taken up in the line 78, until the scraper has reached a position substantially in front of the derrick 71, and the movement of the scraper to filling position continued by drawing on the line 73 and paying out the lines ('57 and 78. The filling of the scraper and its movement to the point of discharge on the spoil pile 62 is effected by first drawing on the line 78 in which operation the slack is taken up in line 67 and line 73 paid out, until the scraper in moving to the right in Figs. 8 and 9, passes the corner 6-1 whereupon the movement of the scraper to dumping position is continued by drawing on the line 67 while paying out the lines 73 and 7 8. Thus the line 78 operates alternately to perform the inhaul and back-haul functions, and by its use sliding of any of the lines in engagement with the corner-portion ea is prevented.

Another advantage resulting from the employment of my invention is that the scraper, by proper selection of the rope speeds of the respective drums, may be caused to travel in portions of its forward and back movements at different speeds without requiring the use of multiple-speed hoisting drums.

While I have illustrated and described certain particular embodiments of my invention and the application thereof to certain uses, 1 do not wish to be understood as intending to limit it thereto as the same may be embodied in other forms of structure and applied to different uses.
